Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello,BAS/ESP light will not come on due to brake pads or rotors. Possibly loose caliper damaged the wheel speed sensor or it's rotor, which can cause these lights to come on. So the distance between the wheel speed sensor and it's rotor, wheel bearing play and the sensor's cabling should be checked. If all is allrgiht there- next step would be to read out and delete the ESP control unit fault codes.
